Three Under 20

Host Mo Rocca shows us incredible innovators under 20 years old; 9-year-old Algae Girl, who is pioneering oil-producing algae by growing it under her bed; how Thomas Edison’s inventions still make us all look like slackers; 16-year-old Hollow Flashlight Girl, who invented a battery-free flashlight; and the 20-year-old from the Netherlands who is skimming the plastics from our oceans.
